Toyota-Lexus-Subaru-Honda Air Intake Tube
Make Sure Your Air Intake Tube is in Good Shape

Honda, Subaru, Toyota, Lexus Air Intake Tube. Make Sure Your Air Intake Tube is in Good Shape. The air intake tube provides passage of air from the air filter housing to the engine. It gets flexed a little back and forth every time you accelerate. Eventually as the rubber gets old and brittle it cracks and splits open. On older vehicles this can make a vacuum leak that significantly affects the idle and lower rpm running.

If your vehicle is an automatic, the poor running can be especially noticeable at stops when you’re car is in drive.

This is because when the split tube opens up, it allows a large vacuum leak. Therefore, as a result, the air that hasn’t passed through the air flow meter to be measured to be matched with the right amount of fuel.

In some vehicles, the type of air-use measuring device (a MAP sensor) doesn’t measure the air by the same means. Above all, in these vehicles the split air intake tube makes absolutely no immediate difference in the way the engine runs in the short term.

However, it allows unfiltered, dirty air into the engine, which causes your engine to wear out more quickly as tiny abrasive particles grind away at the internal moving parts.
